The sample settling time register, listed in
SAMPLE/HOLD signal is asserted before the START signal is asserted, which begins the
conversion. The number of clock cycles required for settling will vary from system to
system depending on the system clock period used. The system designer should program
this register to contain the number of clocks required to meet a 0.5 µs minimum settling
time.
The sample time register, listed in
for the sample after a conversion has begun by setting the START bit in the ADC control
register. The number of system clock cycles required for the sample time varies from
system to system, depending on the clock period used. The system designer should
program this register to contain the number of system clocks required to meet a 1 µs
minimum sample time.
